What exactly is a PF motor? And What does it stand for?
This is one for the top line on CD.
Ok, now to answer the question…
You probably mean FP motor which is referring to the Fisher-Price motor. The motor is actually made by Johnson Electric (I think). These motors mate with the plastic 3 stage transmission in the KOP. Together they are used for the toy jeeps sold through the Fisher Price brand.
And with a pinion change can be mated with other gearboxes, even the banebots…
